Be itl known that I, ELMERL. OGLE, a citi- York, in the-county of New York and State of New York," have invented new and useful Improvements in Radiators, of which fthe following is aspecification.

ators for dissipation or rapid equalization-Of temperature inliquids, gases or vapors, and it has for its object the improvement in eiiiciency, strength. andstiiiness of such radiators, the cheapeningoi their manufacture and the prevention of ill .eiiects resulting' from' corrosive materials which may be brought into contact therewith.

To illustrate one form in which my invention maybe embodied the accompanying drawings are furnished which form a part hereof and in which Figure 1,represents a perspective view of the cooler assembled. Fig. 2, is a section oia art of the'cooler showingthe' grou e ing o certain square tubes forming the bod;r of the cooler. Fig. 3, is a horizontal section throu h a part ofthe cooler. is averticaI deflectors and a portion of the shell. Fig. 5, is a section view showing a construction of the deilector. Fig. 6,'is the front view of one form ofthe cooler. Fig. 7,- is a detail of the ofi-'set lock joint in one 'of the tubes.

'Within the casing or shell A is-secured a group of comparatively short tubes a,l through whic air or other coolin medium may pass and between which the Iiquid to be cooled may circulate in thin films. To create these spaces b between the `tubes a I enlarge one end oie-ach square ltube u on two sides only and then place them side y side alternatelyT as to ends and solder these ends together.

These tubes a must be lthin and consequently fragile if they are to'be elicient..

n my cooler the tubes may be lieldapart l Y in any suitable manner in any event lI do rangement it is also very little enlarv'infr of the tubes and this at b one end only." I can, thus use thinner tubes for my purpose. With thinner tubes, a higher cooling efficiency and a-lightcr cooler may be constructed which Yis very rigid and reliable as to construction. With this arossible to use seained or jointed. tubes a ma e up of very thin sheet steel or other metal, the enlargement c not necessarily coming at the joint itself.

My invention relates to coolersor radi-` Fig.l 4,' section of a portion showing the cure itself with other metals, especially steel, is here utilized to secure' the evident advanta e in When l the tubes are laid up in courses4 vspacersr'may be used as shown 1n Fig. 4, gv

being-eaxplain spacerf'g' a projecting spacer, the prgjection oi which' may be employed as a deiiector for' the air. A ii'liler g see Fig. A5.) is'providediorthe open side of the deiiector.

The tubes are solidly soldered at their ends. To produce a cooler which will withstand high pressure I iind that this soldering should be very deep and thorough'7 and to aocom- .plish this I at iirst found it necessary to 'tin `each. end of eachtube or to use tinned metal tubes. On accountl of vrusting oi the surfaces es ecially-where the tubes are made of steel, I nd it desirable to coat these tubesafter tinning, with copper. f This may be done by electric depositlon of copper or in These tubes will solany suitable manner.

der well owing to the tinning under the. thin Coolers as atpresent employedupon auto-` mobiles niust be so organized as to withstand considerable internal pressure from the cool` ing liquid as well as a vgreat amount ofnieclianical shock and 'an A large part ofthis strain comes upon t e soldered joints which;l

thereiore,.must'be more :than ordinarily-se- The facility with which' tin-alloys employing a cheaper and stiiier meta for tubes while at the same time securing all of likely to be found present in the cooling' Water circulating .in the cooler from vsuch jackets.

It can readily -bev seen that the tubes may be many sided or even round with squared the non-corrosive advantages of copper suror rectangular ends, the' squared ends being preferred.

The operati the foregoing description.

on of the device is evident from islor the rapid dissipation of heat, this being 'accoiniilished by first dividing the lieate medium into thin layers between very thin cooled Walls and cause circulation in irrcgu- Its primary use.

'(See Fi The easing oelell A is 'provided with suitable inlet and discharge openings 'es BB.

.lander -V For t e purpose of illustration-I have de scribed one' construction of my improved cooler. I do not Wish to be limitedto my exact detail or arrangement 'of parts shown es others may be employed end some omitted end the invention extends to' such use.

Having fully described my invention, claim:

l. Steel radiatortnbcs adapted to be united by solder; tinned et be points where they ere to be soldered, in combination with. e superimposed coat of copper over-laying the tube including the tinned surfaces.

2.- Steel radiator tubes adapted to be united by solder; tinned et the points Where they ere to be soldered, in combination with e superimposed, electrolyticelly-deposited, coat of co per over-laying the tube including the tinneg surfaces.

3. A. cooler comprising steel tubes adopted to be united by solder; tinned et the points `where they are/to be soldered, in combination with e superimposed cout of copper overleying tbe tube including the tinncd snreces, the seid tubes being soldered et Llicir ends through the copper coating, substantielly as described.

In testimony whereof l have hereunto set my hand in presence of two subscribing witnesses.
